ISO 6271-2:2004规定了一种分光光度法,用于估算透明液体的颜色,单位为Pt-Co。本标准适用于颜色特征与ISO 6271-1中规定的参考铂钴标度相似的透明液体,该标准描述了一种视觉方法。
与ISO 6271-1中描述的方法相比,所述方法提供了一种更精确的测量铂钴颜色的方法。
ISO 6271-2:2004 specifies a spectrophotometric method for estimating the colour, in Pt-Co units, of clear liquids. It is applicable to clear liquids having a colour characteristic similar to those of the reference platinum-cobalt scale specified in ISO 6271-1, which describes a visual method.
The method described provides a more precise way of measuring Pt-Co colour than that described in ISO 6271-1.
